DB650 EN

SWEP DB650
The DB650 is a highly effective, versatile true dual that is
a natural choice for chillers and heat pump applications. Its
advantage is its ability to offer full performance at both full
and partial load. It is optimized for extreme performance with
refrigerants. The product is approved for pressures of up to
49 bar (710 psi), so it can be used with the majority of current
high-pressure refrigerants, enabling our customers to use the
compressor’s whole envelope. SWEP’s versatile H pressure
products enable efficient heat exchange in applications
combining small flows and high pressures.

The BPHE concept
The Brazed Plate Heat Exchanger (BPHE) is constructed
as a plate package of corrugated channel plates with a filler
material between each plate. During the vacuumbrazing
process, the filler material forms a brazed joint at every
contact point between the plates, creating complex channels.
The BPHE allows media at different temperatures to come
into close proximity, separated only by channel plates that
enable heat from one media to be transferred to the other
with very high efficiency. The concept is similar to other plate
and frame technology, but without the gaskets and frame
parts.
